License requirement check

Item classification and destination. No account needed.

An ECCN (such as 5A992.c) is an exact match and works best. Word search matches the official CCL wording and a reviewed list of everyday names as you write them; it does not guess what you mean or fix spelling. Don’t know the ECCN? Use Find the ECCN.

License requirements

Each control below comes from the entry’s License Requirements table. Where it names a Country Chart column, the countries with an X in that column need a license for the items the control covers, unless a License Exception applies.

  • AT (Anti-terrorism): AT applies to entire entry. A license is required for items controlled by this entry to North Korea for anti-terrorism reasons. The Commerce Country Chart is not designed to determine AT license requirements for this entry. See § 742.19 of the EAR for additional information.
  • RS (Regional stability): RS applies to entire entry. A license is required for items controlled by this entry for export or reexport to Iraq or transfer within Iraq for regional stability reasons. The Commerce Country Chart is not designed to determine RS license requirements for this entry. See §§ 742.6 and 746.3 of the EAR for additional information.

Not decided by the Country Chart: Covered Donetsk region of Ukraine (DNR), Covered Luhansk region of Ukraine (LNR), Crimea region of Ukraine, Cuba, Iran, Korea, North, Syria. These destinations are under embargoes or other special controls in 15 CFR Part 746, which require a license for most items whatever the chart shows. Russia and Belarus also have broad Part 746 controls in addition to the chart.

A blank on the Country Chart is not permission to ship. End-use and end-user rules (15 CFR Part 744), embargoes and sanctions (Part 746), and the parties to the transaction still apply. Use the check above for your item and country.

List-based License Exceptions

As the entry lists them. Each exception has its own conditions in 15 CFR Part 740, and § 740.2 bars or limits most of them for Russia, Belarus, Country Group D:5 and embargoed destinations, so an entry’s “Yes” does not mean it is available everywhere.

  • TSR: N/A

Items in 0D999
